Default Bay boat instability in relatively minor crosswinds

I've owned my Pioneer Baysport 220 for a few years now and the only other boat I' spend much time on is my buddy's much heavier Pursuit.

Overall love the pioneer but if there is any type of crosswind above 10 mph it causes it to list pretty severely. I usually adjust the trim tab on the opposite side as much as needed, sometimes all the way down, to level the boat.

What seems to happen though is if i encounter any wake or wave that causes the boat to lean back into the wind, the wind seems to catch the top of the T-top and push that side down even further into the trough of the wave in conjunction with the trim tab trying to push the same direction. Scares the crap outta my wife.

I'm just wondering if there's something simple I should be doing differently? I.e. trim the motor up/down, have passengers move from the bow to stern, or maybe adjust the tabs differently. Or is this just the nature of a 22 ft bay boat and I need to slow down if I see the situation coming.

what you are experiencing is what is called "broaching " https://en.wikipedia.org/wiki/Broach_(nautical) .

it is usually caused from a inherited bad hull design.

there are ways such as how you are overcoming it but no way to fix it completely...

You are getting bow steer-bay boats with a sharp entry and flatter deadrise are prone to it, it's typically caused by a following sea but can be caused just as you describe.
The condition can be mostly remedied by transferring weight to the stern and reducing the use of tab-keeping the keel forward of the strakes out of the water.

Another method to help is to steer downwind and make the keel cross the wake instead of allowing it to surf down the face of the wave

Ok thx good to know. So instead of worrying about keeping it completely level in a crosswind, ease way off the tabs and let it list naturally a bit in the wind. I always try to hit a wave at 90 degrees to the extent possible.
How much does motor trim matter in this scenario? Trim down so the stern is mostly in the water?

That's bow steer. You are trimmed down too heavily most likely. If you are using tabs to correct the list make sure the other tab is fully up and your motor is trimmed up as well.

Dont stuff your bow!

Could be worth hiring a captain to show you some basics for a few hours?

Good advice above. The nice thing about the hull is that the sharp entry provides a nice ride in choppy conditions, but if you stuff that sharp entry into a quartering wave, particularly in a following sea, the boat will tend to veer off and cause the listing motion. It can be more pronounced when you have a tab down to correct for wind induced list. Depending on conditions, get the bow raised to prevent the sharp entry from "digging in." The faster you run, the more sudden and pronounced that movement can be, so slow your speed based on wave height. You'll get the feel for it if you experiment with different tab and motor settings to see how it changes the running attitude and characteristics in varying sea conditions.

Thanks for the feedback. I definitely understand better what the issue is and can do a couple things differently. Trim up the motor to keep the bow out of the water a little more to avoid bowsteer and less trim tab in these conditions.
